FIG. 1 is a front view of a display screen or portion thereof with a graphical user interface showing a first image of the claimed design;

FIG. 2 is a second image thereof; and,

FIG. 3 is a third image thereof.

The ornamental design that is claimed is shown in solid lines in the drawings. The broken lines in the drawings form no part of the claimed design. Broken lines formed by equal length dashes define the graphical user interface and form no part of the claimed design.

The outermost broken lines in the FIGURES define a display screen or portion thereof and form no part of the claimed design.

The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1-3. The process or period in which one image transitions to another image forms no part of the claimed design.

Grayscale shading illustrates a contrast in appearance, wherein the appearance of different levels of shading indicates a contrast in appearance. 

CLAIM We claim the ornamental design for a display screen or portion thereof with a graphical user interface for displaying financial information, as shown and described.
